The Perfect Sever, Ubuntu 7.10 Postfix issue

I am attempting to configure postfix for my buddies Ubuntu server. He already had all the normal web stuff set up (ftp, PHP, mySQL, ect.) except for postfix.
Having used Falko's guide to set up my Centos server I figured it would be easy.

So I followed Falko's instructions on setting up Postfix With SMTP-AUTH And TLS in Ubuntu Server 7.10 HERE. Everything seemed to go fine. Followed all prompts everything looked good. I installed Courier-POP everything there looked fine.
So I figured I would test the setup. Did this

Ok I figured it out, there was never a problem. I was not attempting to authenticate (postfix wouldn't let me because its not a open relay) once I used a mail client and checked server requires authentication. Worked like a charm.
